Obviously, the embodiments described here are part of embodiments of the present invention and not all of the embodiments.

The technical solutions of the present invention may be applied to various wireless communication systems, for example, a global system for mobile communications (Global System for Mobile Communications, GSM for short) system, a general packet radio service (General Packet Radio Service, GPRS for short) system, a wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA for short) system, or a long term evolution (Long Term Evolution, LTE for short) system, or etc.
Particularly, an access network device can be a base station controller (Base Station Controller, BSC for short) in the GSM system/GPRS system, or can be a radio network controller (Radio Network Controller, RNC for short) in the WCDMA system, or can be a network element, such as an eNodeB in the LTE system, etc.
FIG. 1 is a schematic flowchart of a method for allocating an air interface resource according to an embodiment of the present invention, as shown in FIG. 1, the method for allocating an air interface resource in this embodiment can include:
101, An access network device receives a service state report sent by a UE.
In an optional implementation of this embodiment, before 101, the access network device also can further generate event triggering information or sending period information of the service state report, and then the access network device can send the event triggering information or the sending period information to the UE, so that the UE can send the service state report to the access network device when a condition indicated by the event triggering information is satisfied or a period indicated by the sending period information arrives. In particular, the access network device specifically can send the event triggering information or the sending period information to the UE via a dedicated message, such as a radio resource control (Radio Resource Control, RRC for short) message.
In particular, the access network device can generate the event triggering information or the sending period information of the service state report according to at least one of: a service type of a service used, being used or to be used by the UE, a transmission mechanism adopted by the service type, a service data generating manner of the service type and a QoS parameter corresponding to the service data.
For example, the access network device can receive a command including at least one of the above content, sent by a core network device. Taking the LTE system as an example, the access network device can include, but is not limited to, a mobility management entity (Mobility Management Entity, MME for short), a serving gateway (Serving Gateway, SGW for short), a packet data network gateway (Packet Data Network Gateway, PDN GW for short) or a policy and charging rule function (Policy and Charging Rule Function, PCRF for short); the above command can include, but is not limited to, a bearer establishment message, a bearer modification message, a service establishment message, a service modification message or a control policy configuration message.
It should be noted that, the UE also can configure the event triggering information or the sending period information of the service state report according to a protocol convention.
For example, the access network device can generate the event triggering information or the sending period information of the service state report according to a service type of a service used, being used or to be used by the UE, such as a video (Video) service or a voice over Internet protocol (Voice over Internet Protocol, VoIP for short) service, etc.
For example, the access network device can generate the event triggering information or the sending period information of the service state report according to a transmission mechanism adopted by the service type of a service used, being used or to be used by the UE, such as a real-time transport protocol (Real-time Transport Protocol, RTP for short), a dynamic adaptive streaming over a hyper text transfer protocol (Hyper Text Transfer Protocol, HTTP for short) (Dynamic Adaptive Streaming over HTTP, DASH for short) or a progressive download (Progressive Download), etc.
For example, the access network device can generate the event triggering information or the sending period information of the service state report according to a service data generating manner of the service type of a service used, being used or to be used by the UE, such as an on-demand service, a direct broadcast service, or an interactive service, etc.
For example, the access network device can generate the event triggering information or the sending period information of the service state report according to a service data QoS parameter of the service type of a service used, being used or to be used by the UE, such as a quality class identifier (Quality Class Identifier, QCI for short), an allocation and retention priority (Allocation and Retention Priority, ARP for short), a maximum bit rate (Maximum Bit Rate, MBR for short) or a guaranteed bite rate (Guaranteed Bit Rate, GBR for short), etc.
102, The access network device allocates the air interface resource for the UE according to the service state report.
It should be noted that, the service state report can include, but is not limited to, at least one of the following: the number of video quality conversion times, video play code rate, video play frame delay, packet loss ratio, video play frame rate, video play frame rate deviation, video play waiting time, re-buffering (re-buffering) waiting time/the number of re-buffering waiting times, time interval between request sending and response receiving, average throughput of video service data, buffered data amount or level corresponding to the buffered data amount, buffer play time length or level corresponding to the buffer play time length, and video configuration file information.
It should be noted that, the service state report can include, but is not limited to, at least one of the following:
indication information for indicating video quality conversion event occurring;
indication information for indicating video play code rate event occurring;
indication information for indicating video play frame delay event occurring;

indication information for indicating transmission delay event occurring;
indication information for indicating average throughput of video service data event occurring;
indication information for indicating buffered data amount event occurring; and
indication information for indicating buffer play time event occurring.
In an optional implementation of this embodiment, the event triggering information of the service state report can be configured as multiple forms.
For example, in order to prevent the UE from frequently converting between high video quality and low video quality during video playing, the UE can be configured to report the number of video quality conversion times during video playing. Optionally, a threshold for the number of video quality conversion times (that is, a value in a specified time range) also can be configured, when the number of video conversion times is greater than or equal to the threshold, a service state report including the number of video quality conversion times or further including indication information for indicating video quality conversion event occurring is triggered. Further, the service state report can also include at least one of an identifier of the converted video quality and a video play time for the video quality being converted to. During video playing, the UE can adjust video quality of the played video according to the measured channel bandwidth change, for example, the UE selects to play a low quality video in case the channel bandwidth is unknown, during the playing, if sensing the channel bandwidth is increased through the measurement to the channel bandwidth, the UE can select to play a higher quality video in the subsequent video playing, the higher quality video needs a higher channel bandwidth; if sensing the channel bandwidth is reduced, the UE can select to play a lower quality video segment in the subsequent video playing, thereby causing quality change of the video playing.
For another example, in order to control the video play code rate of the UE during video playing, the UE can be configured to report the video play code rate during video playing. In particular, triggering condition information for the video play code rate event can be configured to the UE, for example, at least one of a maximum value and a minimum value for the video play code rate can be configured, when the video play code rate is greater than or equal to the maximum value (or when the video play code rate is less than or equal to the minimum value), a service state report including the video play code rate or further including indication information for indicating video play code rate event occurring is triggered.
For another example, in order to control the delay during video playing, the UE can be configured to report the video play frame delay during video playing, that is the difference between an actual frame play time and a play time point under normal condition, which can be advanced time for frame playing, or delayed time for frame playing. In particular, triggering condition information for the video play frame delay event can be configured to the UE, for example, at least one of maximum advanced time and maximum delayed time for the video playing can be configured, when the actual play time is greater than or equal to the maximum advanced time (or when the actual play time is greater than or equal to the maximum delayed time), a service state report including at least one of the frame play advanced time and the frame play delayed time or further including indication information for indicating video play frame delay event occurring is triggered.
For another example, in order to control the packet loss ratio of transmission, the UE can be configured to report the case of received packet loss, i.e., to report the packet loss ratio of the received data, and the packet loss ratio can be a fame loss ratio, a bad frame ratio, a block loss ratio, a bad block ratio, a RTP packet loss ratio, a TCP retransmission ratio, an IP packet loss ratio, a packet data convergence protocol (Packet data convergence Protocol, PDCP for short) packet loss ratio, a radio link control (Radio Link Control, RLC for short) packet loss ratio, a RLC packet retransmission ratio, a hybrid auto retransmission request (Hybrid Auto Retransmission Request, HARQ) retransmission ratio or a HARQ decoding failure rate and etc. In particular, triggering condition information for the packet loss ratio event can be configured to the UE, for example, at least one of a maximum value and a minimum value for the packet loss ratio can be configured, when the packet loss ratio of the received data is greater than or equal to the maximum value (or when the packet loss ratio of the received data is less than or equal to the minimum value), a service state report including the packet loss ratio or further including indication information for indicating packet loss ratio event occurring is triggered.
For another example, in order to control the play frame rate, the UE can be configured to report the video play frame rate. In particular, triggering condition information for the video play frame rate event can be configured to the UE, for example, at least one of a maximum value and a minimum value for the video play frame rate can be configured, when the video play frame rate is greater than or equal to the maximum value (or when the video play frame rate is less than or equal to the minimum value), a service state report including the video play frame rate or further including indication information for indicating video play frame rate event occurring is triggered.
For another example, in order to control the play frame rate, the UE can be configured to report video play frame rate deviation, that is, a deviation of the video play frame rate relative to a standard normal frame rate. In particular, triggering condition information for the video play frame rate deviation event can be configured to the UE, for example, at least one of a maximum value and a minimum value for the video play frame rate deviation can be configured, when the video play frame rate deviation is greater than or equal to the maximum value (or when the video play frame rate deviation is less than or equal to the minimum value), a service state report including the video play frame rate deviation or further including indication information for indicating video play frame rate deviation event occurring is triggered.
For another example, in order to control the initial waiting time for the video playing, the UE can be configured to report video play waiting time, that is, a time delay from the beginning of the user selecting to play the video to the video playing. In particular, triggering condition information for the video play waiting event can be configured to the UE, for example, at least one of a maximum value and a minimum value for the video play waiting time can be configured, when the video play waiting time is greater than or equal to the maximum value (or when the video play waiting time is less than or equal to the minimum value), a service state report including the video play waiting time or further including indication information for indicating video play waiting event occurring is triggered.
For another example, in order to control the play interruption caused by waiting for the video data during video playing, the UE can be configured to report the video play re-buffering (re-buffering) waiting time/the number of the video play re-buffering waiting times, that is, video play interruption time caused by waiting for the video data. In particular, triggering condition information for the re-buffering event can be configured to the UE, for example, at least one of a maximum value and a minimum value for the re-buffering waiting time can be configured, when the video play re-buffering waiting time is greater than or equal to the maximum value (or when the video play re-buffering waiting time is less than or equal to the minimum value), a service state report including the video play re-buffering waiting time or further including indication information for indicating video play re-buffering event occurring is triggered. For example, a threshold for the number of re-buffering waiting times also can be configured, when the number of video play re-buffering waiting times is greater than or equal to the threshold, a service state report including the number of video play re-buffering waiting times or further including indication information for indicating the video play re-buffering event occurring is triggered.
For another example, in order to control the video transmission delay, the UE can be configured to report the time interval between request sending and response receiving, for example, a time interval between a certain HTTP request and an HTTP response, or a time interval between a TCP request and a TCP response. In particular, triggering condition information for the transmission delay event can be configured to the UE, for example, at least one of a maximum value and a minimum value for the time interval between request sending and response receiving can be configured, when the time interval between request sending and response receiving is greater than or equal to the maximum value (or when the time interval between request sending and response receiving is less than or equal to the minimum value), a service state report including the time interval between request sending and response receiving or further including indication information for indicating transmission delay event occurring is triggered. Further, the service state report also can include request sending time and response receiving time, so as to calculate the time interval between request sending and response receiving at a network side.
For another example, in order to control the video play bandwidth, the UE can be configured to report the average throughput of video service data, which can be an IP data packet throughput, or a TCP/IP data packet or UDP/IP data packet throughput, and this embodiment is not limited thereto. In particular, triggering condition information for the average throughput of video service data event can be configured to the UE, for example, at least one of a maximum value and a minimum value for the average throughput of video service data can be configured, when the video play average throughput is greater than or equal to the maximum value (or when the video play average throughput is less than or equal to the minimum value), a service state report including the average throughput of video service data or further including indication information for indicating the average throughput of video service data event occurring is triggered.
For another example, in order to obtain buffer information, the buffer can be divided into multiple levels according to the size of buffered data amount, and the UE can be configured to report a level corresponding to the buffered data amount or can be configured to directly report the buffered data amount. In particular, triggering condition information for the buffered data amount event can be configured to the UE, for example, at least one of a maximum value and a minimum value for the buffer can be configured, when the buffered data amount or the level corresponding to the buffered data amount is greater than or equal to the maximum value (or when the buffered data amount or the level corresponding to the buffered data amount is less than or equal to the minimum value), a service state report including the buffered data amount or the level corresponding to the buffered data amount or further including indication information for indicating the buffered data amount event occurring is triggered.
For another example, in order to obtain buffer information, the buffer can be divided into multiple levels according to the buffer play time length available for the current video to be played from the beginning of the current playing time point, and the UE can be configured to report a level corresponding to the buffer play time length from the beginning of the current playing time point, or can be configured to directly report the buffer play time from the beginning of the current playing time point. In particular, triggering condition information for the buffer play time event can be configured to the UE, for example, at least one of a maximum value and a minimum value for the buffer play time range can be configured, when the buffer play time length in the video buffer or the level corresponding to the buffer play time length in the buffer is greater than or equal to the maximum value (or when the buffer play time length in the video buffer or the level corresponding to the buffer play time length in the buffer is less than or equal to the minimum value), a service state report including the buffer play time length in the video buffer or the level corresponding to the buffer play time length in the buffer or further including indication information for indicating the buffer play time event occurring is triggered.
For another example, in order to obtain more video information, the UE can be configured to report video configuration file information, such as quality information of the video to be requested or of the candidate video, required bandwidth information or video play encoding information, etc.
In an optional implementation of this embodiment, video viewing time of the user can be further divided into multiple time periods, so that the UE can respectively perform statistics on the service state information within one time period, so as to generate a service state report. Optionally, the service state report further can include time information, such as the length of the time period or starting time and ending time of the time period, etc.
In an optional implementation of this embodiment, before 101, the access network device also can further send granularity information to the user equipment, so that the user equipment can send a service state report corresponding to the granularity information to the access network device. For example, the service state report can be configured according to a granularity of a video media, that is, to report service state information of a certain video media; or can be configured according to a granularity of a video session, that is, to report service state information of the video in one video session; or can be configured according to a granularity of a bearer, that is, to report service state information of the video in one bearer.
In an optional implementation of this embodiment, if the service state report, received by the access network device, indicates that the video play re-buffering event occurs for many times, or the video play re-buffering waiting time included in the service state report is relatively long, then the access network device can allocate more air interface resources faster for the UE in the subsequent scheduling, so as to improve scheduling priority of the UE or scheduling priority of the bearer.
In an optional implementation of this embodiment, the access network device can further allocate the air interface resource for the UE in combination with a QoS parameter corresponding to the downlink service data to be sent to the UE, which can further provide the end-to-end transmission guarantee between a service server and the UE for the downlink service data. For example, if the service state report, received by the access network device, indicates that the video play re-buffering event occurs for many times, or the video play re-buffering waiting time included in the service state report is relatively long, then the access network device can allocate more air interface resources faster for the UE in the subsequent scheduling according to the QoS parameter, such as delay etc., on the premise of ensuring the service quality of the video service, so as to improve scheduling priority of the UE or scheduling priority of the bearer.
In this embodiment, the access network device receives a service state report sent by the UE, so that the access network device can allocate the air interface resource for the UE according to the service state report, and thus being capable of solving the problem in the prior art that a method for allocating an air interface resource can provide transmission guarantee only for downlink service data on the air interface. By means of the technical solutions provided in the present invention, the end-to-end transmission guarantee between a service server and a UE can be provided for the downlink service data, thereby improving the service quality of the end-to-end transmission.

For example, a threshold for the number of re-buffering waiting times also can be configured, when the number of video play re-buffering waiting times is greater than or equal to the threshold, a service state report including the number of video play re-buffering waiting times or further including indication information for indicating the video play re-buffering event occurring is triggered.
For another example, in order to control the video transmission delay, the UE can be configured to report the time interval between request sending and response receiving, for example, a time interval between a certain HTTP request and an HTTP response, or a time interval between a TCP request and a TCP response. In particular, triggering condition information for the transmission delay event can be configured to the UE, for example, at least one of a maximum value and a minimum value for the time interval between request sending and response receiving can be configured, when the time interval between request sending and response receiving is greater than or equal to the maximum value (or when the time interval between request sending and response receiving is less than or equal to the minimum value), a service state report including the time interval between request sending and response receiving or further including indication information for indicating transmission delay event occurring is triggered. Further, the service state report also can include request sending time and response receiving time, so as to calculate the time interval between request sending and response receiving at a network side.
For another example, in order to control the video play bandwidth, the UE can be configured to report the average throughput of video service data, which can be an IP data packet throughput, or a TCP/IP data packet or UDP/IP data packet throughput, and this embodiment is not limited thereto. In particular, triggering condition information for the average throughput of video service data event can be configured to the UE, for example, at least one of a maximum value and a minimum value for the average throughput of video service data can be configured, when the video play average throughput is greater than or equal to the maximum value (or when the video play average throughput is less than or equal to the minimum value), a service state report including the average throughput of video service data or further including indication information for indicating the average throughput of video service data event occurring is triggered.
For another example, in order to obtain buffer information, the buffer can be divided into multiple levels according to the size of buffered data amount, and the UE can be configured to report a level corresponding to the buffered data amount or can be configured to directly report the buffered data amount. In particular, triggering condition information for the buffered data amount event can be configured to the UE, for example, at least one of a maximum value and a minimum value for the buffer can be configured, when the buffered data amount or the level corresponding to the buffered data amount is greater than or equal to the maximum value (or when the buffered data amount or the level corresponding to the buffered data amount is less than or equal to the minimum value), a service state report including the buffered data amount or the level corresponding to the buffered data amount or further including indication information for indicating the buffered data amount event occurring is triggered.
For another example, in order to obtain buffer information, the buffer can be divided into multiple levels according to the size of the buffer time available for the current video to be played, and the UE can be configured to report a level corresponding to the buffer play time length, or can be configured to directly report the buffer play time. In particular, triggering condition information for the buffer play time event can be configured to the UE, for example, at least one of a maximum value and a minimum value for the buffer play time range can be configured, when the buffer play time length in the video buffer or the level corresponding to the buffer play time length in the buffer is greater than or equal to the maximum value (or when the buffer play time length in the video buffer or the level corresponding to the buffer play time length in the buffer is less than or equal to the minimum value), a service state report including the buffer play time length in the buffer or the level corresponding to the buffer play time length in the buffer or further including indication information for indicating the buffer play time event occurring is triggered.
For another example, in order to obtain more video information, the UE can be configured to report video configuration file information, such as quality information of the video to be requested or of the candidate video, required bandwidth information or video play encoding information, etc.
In an optional implementation of this embodiment, video viewing time of the user can be further divided into multiple time periods, so that the UE can respectively perform statistics on the service state information within one time period, so as to generate a service state report. Optionally, the service state report further can include time information, such as the length of the time period or starting time and ending time of the time period, etc.
In an optional implementation of this embodiment, before 201, the UE also can further receive granularity information of the service state report sent by the access network device; correspondingly, in 201, the UE specifically can generate a service state report corresponding to the granularity information. For example, the service state report can be configured according to a granularity of a video media, that is, to report service state information of a certain video media; or can be configured according to a granularity of a video session, that is, to report service state information of the video in one video session; or can be configured according to a granularity of a bearer, that is, to report service state information of the video in one bearer.
In this embodiment, the UE generates the service state report, and sends the service state report to the access network device, so that the access network device can allocate the air interface resource for the UE according to the service state report, and thus being capable of solving the problem in the prior art that a method for allocating an air interface resource can provide transmission guarantee only for downlink service data on the air interface. By means of the technical solutions provided in the present invention, the end-to-end transmission guarantee between a service server and a UE can be provided for the downlink service data, thereby improving the service quality of the end-to-end transmission.
